Chevrolet Performance 502 C.I. 406HP Truck Replacement Crate Engine.
The Chevrolet Performance HT502 crate engine (19433156) delivers 406 horsepower and 541 lb.-ft. of torque in a durable big-block package built specifically for hardworking trucks. This 502 C.I. engine provides more pulling power and reliability than a stock rebuild while remaining compatible with regular pump fuel thanks to its 8.75:1 compression ratio. A cast-iron 4-bolt main block and all-forged rotating assembly provide the strength needed for towing and heavy use. The hydraulic roller cam keeps maintenance low while delivering strong low- and mid-range torque where trucks need it most. This engine arrives with cylinder heads and balancer installed, allowing you to finish it with your choice of induction and accessories.
